(b) : Totipotency is the ability of a living somatic plant cell to develop into a complete plant. It was first demonstrated by Steward et. al (1964) using phloem cells of carrot. This technique is now used for multiplying rare and endangered plants through micro-propagations. This technique is widely used for multiplying plants e.g., Chrysanthemum, Dioscorea floribunda, Coleus, Crotons, carnation plants etc.
